		+	:Not about to do the sums, but for the earth-end fraction of Earth-fulcrum-person lever to move a distance, the person-end fraction must move distance*ratio(PEF,EEF). For fulcrum-Earth-person length=PEF, rather than length=(PEF+LEF), for a shorter lever due to re-using the fulcrum-Earth length, so that's perhaps the more economical setup.
		+	:You need to swing a lever more than 60° (±30° from a given tangent) around its pivot to get the contact-point travel to go further than the length from pivot to CP (straight-line difference, or length*pi/3 tracing the radius), but at decreasing returns (you could never lever by more than twice the length (straight) or pi times it (semicircumferentially) from the pivot, at ±90° travel), so we might assume we set it up to do no more (though we could also calculate for the maximum).
		+	:This sets us the distance from fulcrum to Earth, and then the force-multiplication needed for an average human's applicable strength is also the length-multipliple needed for fulcrum to person, allowing us to choose (according to setup, but in both cases overwhelmingly the fulcrum-person distance, so barely different) the appropriate full lever-length. And, having constrained the travel-angle, the person's travel-length (radially?) is directly calcuable.
		+	:Or, to reverse, perhaps we can discover what assumptions that the Earth-moving figures might have arisen from. The simplest might be what angle of pivot it is, though not knowing if it's radial or direct displacement they give introduces us a small uncertainty, as does the order of contact-points. Less so than the force-multiplier demanded, though, given variations of human physiology. [[Special:Contributions/172.70.86.4\|172.70.86.4]] 09:02, 7 September 2022 (UTC)
